Have you ever asked yourself what penguins do all day? No? Well, they really seem to live the most adorable lives ever. They wake up, greet the sunrise, eat, laugh, play, and socialize with their friends. They're just about the cutest animals we rarely get to interact with.

In celebration of Penguin Awareness Day (January 20th), we've put together some fun facts, and a very cool collection of royalty-free penguin photos. Each one is available for downloading. Enjoy.

Male penguins that are fatter are actually more desirable as a mate, given that their excess skin can serve as an "egg warmer" while their females go hunting, often for months at a time.
